Gill Heart & Vascular Institute Faculty Publications

Background: Dual antiplatelet therapy (DAPT) following percutaneous coronary intervention (PCI) remains a cornerstone for preventing ischemic events; however, the optimal long-term single antiplatelet therapy after completion of DAPT remains unclear. We aimed to compare clopidogrel and aspirin monotherapy after completion of the standard duration of DAPT.

Methods: A systematic search was conducted on PubMed, Scopus, Cochrane Library, and Web of Science from inception to April 2025. We included randomized clinical trials and observational studies that compared aspirin versus clopidogrel monotherapy after completion of standard-duration DAPT. The primary and co-primary outcomes were major adverse cardiovascular events (MACE) and major bleeding, respectively. …

Dark And Camouflaged Genomic Regions Remain Challenging In Chm13, Mark E. Wadsworth, Madeline L. Page, Bernardo Aguzzoli Heberle, Justin B. Miller, Cody J. Steely, Mark T. W. Ebbert

Sanders-Brown Center on Aging Faculty Publications

Comprehensive genomic analysis is essential for advancing our understanding of human genetics and disease. However, short-read sequencing technologies are inherently limited in their ability to resolve highly repetitive, structurally complex, and low-mappability genomic regions, previously coined as “dark” regions. Long-read sequencing technologies, such as PacBio and Oxford Nanopore Technologies (ONT), offer improved resolution of these regions, yet they are not perfect. With the advent of the new Telomere-to-Telomere (T2T) CHM13 reference genome, exploring its effect on dark regions is prudent. In this study, we systematically analyze dark regions across four human genome references—HG19, HG38 (with and without alternate contigs), and …

Data-Driven Thresholds For Standardized Classification Of Severe Alzheimer’S Disease Neuropathology Using Digital Neuropathology, Ryan K. Shahidehpour, Allison M. Neltner, Mitchell A. Klusty, Cole Corbett, Angelique D. Gonzalez, David A. Gutman, David W. Fardo, Adam D. Bachstetter, Cody Bumgardner, Margaret E. Flanagan, Peter T. Nelson

Sanders-Brown Center on Aging Faculty Publications

Alzheimer's disease neuropathological changes (ADNC)—operationalized with semi-quantitative parameters—represent the consensus-based gold standard for diagnostic evaluation of disease severity. Although useful, ADNC diagnostic frameworks have limitations, particularly in advanced disease stages where pathological severity varies widely within a given diagnostic category. Further, some individuals lacking cognitive impairment are inappropriately categorized as having severe ADNC. In this study, quantitative pathology metrics and alternative tissue sampling schemes were integrated with data about premortem cognitive status, in order to derive clinically informed neuropathologic diagnostic thresholds. Specific goals of the current study were to generate data-driven, standardized diagnostic cut-points, with the most severe stages of …

Clonal Expansion Of Cytotoxic Cd8⁺ T Cells In Lecanemab-Associated Aria, Lance A. Johnson, Kai Saito, Akhil V. Pallerla, Jessica L. Funnell, Ashley R. Ezzo, Chelsea M. Song, Douglas A. Harrison, Noah J. Norton, Lauren C. Moore, Linda J. Van Eldik, David W. Fardo, Greg E. Cooper, Josh M. Morganti

Sanders-Brown Center on Aging Faculty Publications

Amyloid-related imaging abnormalities (ARIA) are the principal safety concern limiting anti-amyloid therapies for Alzheimer’s disease, yet their biology remains unclear. Here we show, through multi-omic profiling of peripheral blood from three ARIA+ patients and matched controls, that ARIA is associated with coordinated reprogramming of CD8 + T cells. CD8+ effector memory (TEM) and terminally differentiated (TEMRA) subsets were expanded, clonally enriched, and transcriptionally primed for cytotoxicity and vascular trafficking. Transcription factor inference and metabolomics converged on glycolytic reprogramming favoring short-lived effector function. Ligand-receptor modeling revealed enhanced monocyte-to-T cell signaling through antigen presentation, adhesion, and chemokine axes, while integration with a …

Knowledge Based Automated Planning For Non-Coplanar Vmat Stereotactic Radiosurgery In Ocular Malignancies, Chase Cochran, Shane Mccarthy, William St. Clair, Damodar Pokhrel

Radiation Medicine Faculty Publications

Background and Purpose: Stereotactic radiosurgery/radiotherapy (SRS/SRT) has emerged as a less invasive alternative to enucleation in the management of ocular malignancies. SRS/SRT planning is time-consuming, complex, and the plan quality depends on the experience of the treatment planner. We demonstrate the use of RapidPlan modeling in conjunction with HyperArc for the treatment of ocular diseases to improve planning efficiency, consistency, and quality.

Materials and Methods: A HyperArc-based RapidPlan (HARP) model was iteratively trained on 80 patient datasets that simulated ocular malignancies. Twenty additional patient datasets were reserved for model testing and comparison with manual plans. Each testing dataset was both …

Radiation Medicine Faculty Publications

Designing and interpreting early phase trials of theranostic radiopharmaceuticals remains challenging because it is difficult to isolate effective levels of activity in enriched patient populations that would be worth following up in later-phase development. This study explores the known challenges and emerging opportunities for clinical research on patients with uterine cervical cancer. We identified eight randomized combination trials for advanced-stage uterine cervix cancer that were activated between 2011 and 2022 and tabulated their results to determine whether combinations were better than individual constituents and which suitable study population is best situated for the study of a new theranostic agent. In …

Reverse Koebner Phenomenon In Linear Scalp Morphea Following Punch Biopsy: A Rare Therapeutic Response, Suhas C. Gowda, Akshay Samagani, Shreyas C. Gowda

Digital Journal of Clinical Medicine

Morphea is a chronic immune-mediated fibrosing disorder characterized by excessive collagen deposition in the skin. Linear morphea of the scalp (en coup de sabre) commonly demonstrates the Koebner phenomenon, wherein lesions develop at sites of trauma; however, the reverse Koebner phenomenon—trauma-induced regression—is exceptionally rare. We report an unusual case of linear scalp morphea showing early regression following a diagnostic punch biopsy. A 71-year-old male presented with an asymptomatic, indurated linear plaque on the scalp of two months’ duration. Histopathology from a 3.5-mm punch biopsy confirmed morphea, demonstrating dense collagen bundles with lymphoplasmacytic infiltrate. At follow-up eight days after …

Cerebellar Deep Brain Stimulation Rescues Purkinje Cell Mitochondrial Density In A Genetic Mouse Model Of Cerebellar Ataxia, Lauren N Miterko-Myers, Lauren E Peacoe, Lita Duraine, Zhongyuan Zuo, Roy V Sillitoe

Faculty, Staff and Students Publications

Deep brain stimulation (DBS) improves motor function in a growing list of movement diseases including Parkinson's disease, dystonia, and tremor. There is evidence that DBS may also be effective in ataxia. It is not known why DBS is effective, but modulating cell activity and conferring neuroprotection are hypothesized to underlie its benefits. Understanding the effects of DBS on neurons is paramount to extending its clinical use in the treatment of various motor and non-motor diseases. Here, we stimulated the cerebellum of Car8 waddles (Car8wdl) mice, given the cerebellum's important role in ataxia pathophysiology. Using transmission electron microscopy, we tested the …

School of Medicine Student Publications and Presentations

Background: Major lower extremity amputations are associated with substantial postoperative morbidity and mortality (Belmont). Restrata is a synthetic electrospun fiber matrix that is engineered to closely resemble human extracellular matrix to facilitate wound healing while avoiding the drawbacks of traditional biologic wound matrices (MacEwan, Fernandez). There have been no studies which have directly compared micronized electrospun fiber matrix (MEFM) to biologic xenograft matrices in patients undergoing major lower extremity amputation. The purpose of this study is to compare postoperative wound recovery in patients undergoing major lower extremity amputation, treated with MEFM (Restrata Minimatrix, Acera, St.Louis, Missouri ) versus a type …
